Question

resolva as equações:

x + 5 = 8

x - 4 = 3

x + 6 = 5

x - 3 = -7

x + 9 = -1

x + 28 = 11

x - 109 = 5

x- 39 = -79

10 = x + 9

15 = x + 20

4 = x - 10

7 = x + 8

0 = x + 12

-3 = x + 10​

Answer 1

x +5= 8

x = 8-5

x = 3

x-4=3

x = 3+4

x = 7

x +6=5

x = 5-6

x = - 1

x -3=-7

x = -7+3

x = -4

x+9= -1

x = -1-9

x = -10

x+28= 11

x = 11 -28

x = - 17

x -109= 5

x = 5+109

x = 114

x-39= -79

x = -79 +39

x = - 40

10-9= x

x = 1

15-20= x

x = -5

4+10= x

x = 14

7-8= x

x = -1

0= x+12

-12= x

x = -12

-3-10= x

x = -13
